We developed a molecular-grafting procedure to the synthesis of ultrathin Fe3O4 decorated Fe3O4/silica core/shell nanoparticles. Such nanoparticles demonstrated superparamagnetic transitions at temperatures of 14 K and 213 K and weak magnetic interactions between the decorated ultrathin Fe3O4 and Fe3O4 cores. When evaluated for the electromagnetically/pH switchable drug delivery, the Fe3O4/silica/Fe3O4 nanoparticles manifest a better controllability for enhancing the drug release than the Fe3O4/silica nanoparticles, ascribed to the bimodal hyperthermia effect of internal ~10 nm Fe3O4 cores and externally decorated ~2.5 nm Fe3O4 nanoparticles.
